Meh... Best Buy isn't bad if you need it right now. I'm lucky enough to have a TigerDirect.com store in my area, so I usually go there and I haven't bought anything in BB in months except for a router which I needed the same day.
I have an Acer Aspire that I use for work(I work remotely, use IM, run VOiP applications and Citrix, and at times use Word.) I also use it when I'm not working for basic video editing, and of course, web surfing.
Similar to mine, which I got last year around this time
Mine has an Intel processor in it, but it hasn't given me any hiccups at all, outside of some minor times where the screen has shut off and I got a "video card cooling" message but that hasn't happened in forever.
I had a Thinkpad back in the day, before IBM went Lenovo. Was a great laptop.
Honestly though if I had to do it over again I am INCREDIBLY satisfied with my Acer. Should be fine for what your wife needs.
